COMBINED. GIVEN AND .STOVE-PIPE DRUM.

-4 Q The Schedule referred to in theseLetters Patent and making part of the same.

To all persons to whom these presents 'may come:

Be it known that I, JOHN W. GLOUGH, of Montville, in the county of Waldo, and State of Maine, have made a new and useful invention, having reference to Radiators for Stove-Pipes; and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure l is a vfront elevation,

Figure 2, a vertical and longitudinal section,

Figure 3, a transverse and vertical section, and

Figure 4, a horizontal section of it.

The body of the radiator consists of two concentric drums, A B, arranged as represented, so that there may be a flue-space encompassing the inner and Within the outer of such drums.

Such flue-space is closed both in front and in rear by,

the heads a b of the outer drum.

The inner drum, which is intended for use as an oven, extends from one of such heads to the other, and is open at its front end, to which a door, C, is appliedso as to swing on a hinge, c.

There extends vertically through the flue-space an annular partition, il, by which the space surrounding the inner drum is divided into tWo lues, D E, Which communicate with each other by means of an opening, F, made in the partition.

Furthermore, the back ilue E -is divided by a second ary, or lesser, partition, p, which. goes across itand the opening F, it being arranged so as to cause any cury rent of smoke, when passing through the opening F, to be so divided as to pass entirely around the oven,

and equally heat that portion of its external surface which may be Within the back flue. l

.Ihe secondary, or lesser partition p, is to prevent the smoke, after going through the opening F, and into the back flue, from coursing in one direction only about the oven, as it would otherwise be ,likely to do.

An induction or entrance-pipe, G, leads into the lower part of the front flue, yand the rear flue, at its top, opens into an eduction-pipe, H, disposed so as to project from the upper part of the outer drum.

A damper or swing-valve, I,'is arranged in the lower part of the front iiue, and, with respect to the induction-opening thereof, in manner as represented.

lhe spindle e of the damper comes through the front end of the outer drum, and is provided with a handle, j'.

By turning this damper into the inclined position, as shown by the dotted line, atg, smoke, after entering the front flue-space D, will be caused to pass entirely around the oven, and thence through the opening F, and thence'in the fine-space E, and again around the oven,and finally through the eduction-passage.

But by turning the damper into the position indicated by the dotted line h, the smoke will be caused to pass directly into the opening F, Without going around the oven.

The smoke, in passing through the ues, will notonly heat the oven, but willximpart heat to the outer drum, from Whose external surface'the heat will be radiated.

The said oven and radiator combined are intended for use in the escape-pipe or funnel of a stove, which pipe is to lead or open into the induction-passage, and out of the eduction-passage of the oven andradiator.

When the oven is'not require'd for baking, its door may be left open, in which case the heat radiated intothe oven may be employed to advantage in heating the apartment in which the radiator may be placed.

I claim the arrangement and combination of the annular partition (l and its opening F, with the two concentric drums A B, the damper I, and the induction and eduction-openings or pipes G' H, the whole being substantially as set forth.

I also claim the combination and arrangement of the secondary, or lesser partition p, with the annular par# tition d and its opening F, the two concentric drums A B, the damper I, and the induction 'and eductionpassages or pipes G H, arranged substantially as specifle JUHN W. GLOUGH. Witnesses:
